Statistical Inference

• Use statistic of a sample $\bar{x}$ to estimate parameter of population $\mu$.
• Confidence Interval (CI) is an interval expected to contain the parameter being estimated.
• Given a Confidence Level (CL) $\gamma \%$, a random CI should contain $\mu$ being estimated $\gamma \%$ of time.
• Bootstrap: sampling with replacement
• Normality Test
  • Q-Q plot
  • Shapiro-Wilk Test
• Correlation
